Sony is recalling its VAIO Flip PC laptops as their lithium-ion batteries can overheat, posing fire and burn hazards.

The specific laptops were sold at Sony retail stores in the U.S. and online at www.store.sony.com from February 2014 to April 2014 for about $800.

This recall includes Sony's VAIO Flip PC laptops with model number (product name) SVF11N13CXS. The silver, black and pink computers were sold at Sony retail stores in the U.S. and online at www.store.sony.com from February 2014 to April 2014 for about $800.

They have a Panasonic-manufactured lithium-ion battery and a folding touch screen that measures about 11.6 inches diagonally and a backlit keyboard. The model and serial numbers are printed on a black label with white lettering on the underside of the screen.

Sony says it is aware of four incidents, which occurred in Asia, of computers overheating, resulting in units smoking, catching on fire and melting. No injuries have been reported.

Consumers should stop using the recalled personal computers and contact Sony for instructions on how to arrange for an inspection free of charge to the consumer and a free repair or full refund of the computer's purchase price.
